MACHINE FOR PRODUCING SEWING-RIBS ON THE SOLES OF BOOTS AND SHOES.

Patented- Dec. 3, 1907.

Application filed May 10. 1907. Serial No. 372.988.

T 0 all whom it may concern:

Be it known that I, WILHELM NowoTNY, a subject of the Emperor ofAustria-Hungary, and resident of The Limes, Street, in the county ofSomerset, England, mechanic, (whose post-oflice address is The Limes,Street, county of Somerset, England) have invented a new and usefulImproved Machine for Producing Sewing-Ribs on the Soles of Boots andShoes, of which the fol,

lowing is a specification.

The subject matter of th1s invention relates to machines for theproduction of sewing ribs on shoe and boot soles asdescribed in BritishPatent No. 13,432 of 1902 and the object of the invention is principallythe improvement and simplification of the machine described in thispatent for the purpose of enabling the working tools to be better andmore quickly adjusted, to suit the different thicknesses of. materialthan is the case in the machine described in British Patent No.13,432/1902. This object is attained by the mounting of the upper presstool in a frame pivoted at its lower part to the upper frame of themachine, and in consequence the tool can be moved towards or away fromtheimmovable upsetting tool without any special adjusting device accord:ing to the thickness of thelateral rim to be bent up, and also bymounting the lower forward feeding tool so as to be capable of movinghorizontally independently of the press tool mounted upon the rockingframe and so that it can be adjusted towards the upsetting tool.

The subject matter of the invention is shown in the drawing.

a is the frame of the machine, I) is the upsetting tool, 0 the upperpress tool and d the lower forward. feeding tool, 6 is a frame pivotedto the frame a of the machine at The lower forward feeding tool d ismounted to rotate in the frame a of the machine and is also adapted tomove horizontally by means of guiding slots and a screw spindle g. Theupper press tool 0 is mounted by means of a sleeve 7L on the rockingframe 6 and can be adjusted up from or down to the forward feeding tool(1 by means of the hand wheel i according to the thickness of the soleto be operated upon. The upsetting tool I) is pivotally mounted at 9' onthe frame a of the machine and has the to and fro swing required forupsetting imparted to it by a groove cam 7c keyed fast upon the drivingshaft Z. The rocking frame 6 is brought back to its initial position bya helical spring m. For determining the extent of the swing of the frameand consequently the strength of the thickening of the sewing rib thereis provided a screw 0 adjustable in'a bearing n on the frame e andbearing against an abutment on the frame of the machine.

For the purpose of constantly keeping up the driving of the upper presstool 0 from the driving shaft Z in the various positions of the rockingframe 6 the bevel wheel gearing 1) which drives the press tool isconnected to the driving shaft Z by a double universal joint g and theaxle of the gear wheel carried by this joint is mounted to rotate in abearing 1" of the upper transverse part of the frame.

The lower forward feeding tool (1 is driven by a horizontal shaft tdriven by means of a bevel Wheel drive 8 off the driving shaft Z.

This shaft t has long teeth at on its other end by means whereof itengages with a ring of teeth v on the forward feeding tool (i, so thatthe tool, when it is moved horizontally by means of the screw spindle git always remains in engagement with the shaft t. The vertical shaft ofthe tool 01 is passed through a bearing to (in which reposes acaoutchouc ring w*) and carries on its lower end hand wheels so foradjusting the forward feeding toolhigher or lower.

The working of the described arrangement of machine for the productionof sewing ribs on shoe soles is as follows :After the sole to beoperated upon has been laid upon the lower forward feeding tool, thelatter is adjusted by means of the screw spindle 9 according to the sizeof the rib to be upset and by means of the hand wheels 90 to the desiredheight with regard to the upsetting tool I). The extent of swing of theframe 6 and consequently the pressure of the sole against the upsettingtool is then regulated by means of the set screw 0 and finally thethickening of the sewing rib is determined by suitably adjusting theheight of the upsetting tool by means of the hand wheel t, after whichthe driving shaft 1 is set in motion in the usual way, the lower forwardfeeding tool (1 and the upper press tool being set in rotation by thedescribed gear wheel train 8, u, and p and the upsetting tool b setswinging by the groove cam is.

As the upsetting tool I) has no adjusting device to wear out during theworking of the machine and as the upper press tool 0 presses against theu setting tool 6 during the oscillation of the ame and as finally theworking (operative) edge of the press tool always preserves the sameinclination to the upsetting tool I), a very neat uniform product isobtained with the described arrangement. Finally in consequence of theelastic mounting of the forward feeding tool cl owing to the rubber ringinserted in its bearings, too strong a pressing action and damage of thesole to be operated upon or of the tool also is avoided.

What I claim as my invention and desire to secure by Letters Patentis 1. A machine for producing sewing ribs for boot and shoe solescomprising a stationary frame, an upper press tool, a lower forwardfeeding tool, an upsetting tool, a swinging frame for carrying the upperpress tool and means for pivoting the said frame at its lower end to thestationary frame substantially as described.

a 2. A machine for producing sewing ribs for boot and shoe solescomprising an upper press tool, a lower forward feeding tool, anupsetting tool and a swinging frame carrying the upper press tool, adriving shaft for the machine and a universally jointed shaft interposedbetween the said driving shaft and the upper press tool substantially asdescribed.

3. A machine for producing sewing ribs for boot and shoe solescomprising an upper press tool, a lower forward feeding tool', means foradjusting the lower forward feeding tool higher or lower, an upsettingtool, means for adjusting the lower forward feeding tool horizontallywith regard to the end of the upsetting tool and means for imparting aswinging movement to the upsetting tool, substantially as described 4. Amachine for producing sewing ribs for boot and shoe soles comprising anupper press tool, a lower forward feeding tool, an upsetting tool, meansfor adjusting the lower forward feeding tool horizontally with regard tothe end of the upsetting tool and means for supporting the lower forwardfeeding tool elastically substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILHELM NOVVOTNY.
